The use of ion-beam treatment to activate the surface of multiwalled carbon nanotubes in the formation of nanocomposites with tin oxide by chemical gas-phase deposition

Abstract

The possibility of activation of the surface of multi-walled carbon nanotubes by irradiating them with a beam of 5 keV argon ions in the formation of composite with tin oxide (SnOx/MWCNT) by gasphase chemical deposition is studied. The analysis of the structure and chemical state of the formed composites is carried out using synchrotron radiation by X-ray photoelectron spectroscopy (XPS)
and X-ray absorption spectroscopy (XANES). The results obtained showed that the preliminary treatment of MWCNT by argon ions leads to the formation of oxygen-containing functional groups on their surface that act as interphase interaction centers during the subsequent formation of the SnOx/MWCNT composite.
